I just stood next to someone in the marketplace who had used the "Extra Tall Height" item and we appear to be almost the exact same height outside of the "Inspect screen."
For those wondering how I made this conclusion, I measured it from the "Inspect screen" relative to the background, with the EXACT same equipment on, and double-checked my theory via preview in the AH (you can tell from inspect that he is taller, but you can't tell in the open world... which is the primary reason I imagine anyone would get the item?).
Any thoughts on this? It's also noteworthy that the height difference is very obvious when someone is using "Extra Short Height." Why should the "Extra Tall Height" be any different?
I really think it needs to be on par with Feron with the amount of effort it takes to get it. I'd at least like to be bulkier. There is just too little a difference between Tall and Extra Tall.
